Well, In 1966 "AMF" had become AVIS, so I am not sure why it was labeled as such on the map (Corporate Inertia, I suppose). In addition, looking as close as the resolution of the 1966 Historic Aerial I linked to above allows, there was no siding to Avis (which is what I remember from the 1990s as well), and quite frankly that "Arma" siding just heads East to dead end at the newly constructed Zeckendorf Blvd (at a rather high wall as well). In fact, there doesn't seem to be any active sidings north of Zeckendorf, you had the run around which I guess was used to service the siding at Blanchard (Waldbaums siding was accessed from the South). Also, where did Alside come from at the AVIS location? If I wrote that, then forgive me, I don't know where that came from. If Alside predates AVIS (at a minimum NEGATIVE 4 years before the 1966 map), then that pushes AMF back even further (AMF had a location on Jericho Turnpike in Westbury in 1960, I don't have the exact address). The word back in the day was Avis was the site of a defense contractor in WWII (plausible), but I have no confirmation of this.For the record, AAR goes by "AAR Aircraft Services" on their website.

Happened to notice this ebay seller had a number of old slides of the GC Secondary. Some unusual shots. (Might have to be signed in to view completed listings) The two pics of freights are cool. Don't see many shots of them on the branch.
